Forget about my plea. I have used wrong command.

Can you help me, ypool version has stopped working on Ubuntu 13.10. I am getting following message:

spawning 5 worker threads
Segmentation fault (core dumped)

I am using stock Ubuntu 3.10 and Josh Patten Bootstrap mining.

Sorry for the confusion. It seems that I got benefit by increasing engine clock. Reducing memory clock did not increase col/m. But it has slightly reduced temp. As I don't have watt meter, I was a bit conservative with setting.
Main drivers of increased speed are algorithm and engine clock.

I am getting 6830 col/m on 5x Sapphire 7950 with stock settings. That is ~1370 col/m. I have Celeron with 4Gb Ram.

Does anybody knows, how to tweak performance to get closer to 1800 col/m as some users are reporting.

I am using Ubuntu 13.1 with the latest drivers and miner v0.1.3.

Please use v0.1.2 until the next version is released. This should be fastest on your GPU. I'm working on an update with huge performance gains.

v. 0.1.2 with some tweaks I managed to squeeze out 7250 col /m
v. 0.1.4 I am  getting 9300col/m whoa

Slightly decreasing memory clock and increasing engine clock, using  algorithm 1, I managed to increase speed to 10500. Whooha!

After changing to previous version, I  am getting 7250 col/m.

I have changed memory setting on two cards to 975/1475, but there was no improvement. I am running all 5 workers in same terminal. Is there anything else I could change?
